Simplified Information Geometry Approach for Massive MIMO-OFDM Channel Estimation -- Part II: Convergence Analysis
Jiyuan Yang, Yan Chen, Mingrui Fan +3
In Part II of this two-part paper, we prove the convergence of the simplified information geometry approach (SIGA) proposed in Part I. For a general Bayesian inference problem, we…

Group Information Geometry Approach for Ultra-Massive MIMO Signal Detection
Jiyuan Yang, Yan Chen, Xiqi Gao +2
We propose a group information geometry approach (GIGA) for ultra-massive multiple-input multiple-output (MIMO) signal detection. The signal detection task is framed as computing t…

Efficient Information Geometry Approach for Massive MIMO-OFDM Channel Estimation
Jiyuan Yang, Yan Chen, Mingrui Fan +6
We investigate the channel estimation for massive multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. We revisit the information geometry…
